Wide open caliper with brand new pads have 12.8-13.0mm between the two pads. 12mm thick Rotor should work. Depend how your bracket center the galiper compare with Rotor. He have 0.4-0.5mm of play each side.

Good to know. The bracket has the caliper naturally centered, so if the clearance is there, it should be no problem. There is enough float room for it to adjust properly.

As soon as Brian has put his through the paces and I'm satisfied that there will be no issues, I'll start the GP officially, and will post ETA of run completion at that time. I'm hoping we're looking at a mid-late April date, but I want to see how things go first.

Ok heres my official short term review. Theyre holding up so far. I havent had any leaks but I have had a softer pedal than I like. But I think I have air somewhere because everyone else is fine with Saturn calipers. I love how quiet the braking is. Full ceramic pads are so much quieter than a broken shoe and rusty hardware. The ebrake works pretty much like a normal J-body ebrake. It stops quickly even though I do have a soft pedal. It doesnt feel like its dropping in the back when I brake hard.

Installation was simple. It took me 20 minutes on the second side to get everything apart and bolted on and ready to bleed. But bleeding kicks my ass. Im going to pick up some speed bleeders to make my life easier.

The spacing is good if youre running something like a 17x7.5 +35 like I am but it might be too much for people running wider wheels

There is a very close clearance between the caliper bracket and rotor but it does clear as long as you hold the caliper while tightening the bracket or it wants to spin and get up against the hat. But I am also running different rotors than I sent Shawn so there may be a difference in the hat.

Heres how they fit in a 17

I ran 15s for a little while

And theres about a half inch between the banjo bolt and the barrel of the wheel. So they should go on 15s but not 14s so I have to rock multi wheel for a few days until I get tires.

They are 10.6" rotors. I believe the Saturn rotors are 10.0", but someone else may be able to confirm this. The biggest issue was the hat. Since the Saturn rotor doesn't have the internal drum, the hat is considerably smaller, and the caliper bracket has plenty of clearance. When I was designing these, my biggest obstacle was making sure there was enough clearance for the hat while still keeping the entire pad surface on the rotor. It just barely makes it. The brackets can be clearanced slightly at the ends with a little grinding toward the ends. There must be a slight difference in the hats by manufacturer, because there was definitely a little more clearance than that on the rotor Brian sent me originally. I am going to tighten up the tolerance on the caliper bracket mounting holes a little more, though, as this should alleviate the problem of the caliper swinging inward slightly while tightening the bolts.

I wonder if I can turn the center thinner so the wheel wouldn't still out so far?

You mean shave some of the height off the rotor hat? I'm not sure you could safely take enough off to make a difference.

I could make the plates larger and mill a recess for the mounting plate on the axle, but the cost will go up due to larger stock and more machining. This was my original idea, but once I took all the measurements, I opted to keep the cost down.

Well, if you guys would like, I'll do the redesign and get a quote on them. I could feasibly reduce the thickness behind the hub to 3/8" without a problem, but the adapter itself will end up considerably larger in diameter due to the size of the axle plate.

I want mine with the 1/2" spacing. And looking back at my measurements when I was investigating the Neon rotors, it looks like it's a full inch bigger diameter than the Saturn rotors. Should help fill out the rear wheels even more nicely.

Two things brought my attention:
1. That caliper is very close to that hat. I would figure with the heat after some high speed stops, or repeated track stops would make the metal expand causing to rub/scrape. I may be extreme here, but that's what the pics are telling me.

2. Can you use your original spare tire? As the spare should belong there to begin with.

Its not that close that thermal expansion is going to cause rubbing. Ive done several back to back 40-0 stops and there wasnt any rubbing problems. I also do a lot of 'oh @!#$' stops everyday on my way home from work and they performed better than the drums.

I will have to check the donut. It may be shallow enough that it wont hit the caliper or banjo bolt. I was probably just going to make a full size spare though since I have 6 wheels to play with.

The only complaint I have, which is very minor and I need to give some more time to see if it works itself out, is that I can hear the brakes when I hit the pedal when I have the window down. It may be from the pads or the slotted rotors too. Or because the Neon rotors are a slight bit thicker than the Saturns. Either way it really doesnt bother me at all. Its just me being picky.

As I mentioned a few posts up, the caliper is closer to the hat on the rotors that Brian is using now than they were with the factory rotors, so there is obviously a slight variance that people will have to pay attention to, but grinding a little off the caliper bracket where it's closest to increase clearance should not be an issue at all. I'm going to pick up a caliper and rotor to use for testing the redesign to decrease the offset of the hub, and I'll grind that back a little to show how it can be clearanced. I think it will actually look a little better, because the radius of the caliper bracket will be closer to the radius of the hat (if you look, you can see that the bracket is designed for a smaller rotor)
